Shaping member and method

ABSTRACT

The invention relates to the provision of various shapes integral to surface members in architectural walls and ceilings such as building board materials, plaster and cement render. A first aspect relates to a shaping member for forming a smooth and continuous joint between two dissimilar materials in such a manner that the said joint is not normally apparent to the human eye with the intention of shaping the said surface member for the purpose of housing or augmenting the functioning of utilitarian devices such as light fittings, air conditioning registers and/or to provide decorative forms. An advantage of the present invention is that architectural walls and ceilings may be shaped into specific forms in order to direct the emission of light from associated light fittings and the flow of air from ventilation devices, etc. The second aspect relates to the integration of the said shaping member with supporting members and suspension members with which to suspend or otherwise support surface members with the advantage that framing members are reduced in number, construction time reduced and ease of construction increased to achieve the desired aesthetic.

This invention relates to the provision of devices for the shaping of surface members such as wall or ceiling surfaces for the purpose of housing or otherwise augmenting the functioning of various utilitarian devices.

In one aspect, the present invention relates to a method and apparatus for forming specific shapes in surface members (such as wall or ceiling linings) or in the surface of concrete slabs and also to an apparatus and method for housing light fittings, air conditioning registers and other devices used in architectural interiors, which is installed by fixing the same shaping member to the front or rear surface of the same surface member.

In another aspect, the present invention relates to a method and apparatus for suspending and shaping surface members, including building boards such as plasterboard or fibre cement sheeting.

In another aspect, the present invention relates to a method and apparatus for forming specific shapes in concrete slabs (herein called surface members) and also to an apparatus and method for housing light fittings, air conditioning registers, fire extinguishing services and other devices used in architectural interiors, which is preferably installed by using the same shaping member as form work around which the concrete is poured.

Most surface mounted, recessed or semi recessed light fittings and other devices currently available are obviously apparent in the wall or ceiling lining within which the same device is fitted and are obvious attachments to the wall or ceiling. One disadvantage of such a light fitting or device is that a separate housing is necessary to contain the contents of the same fitting and the fitting is perceived as an attachment to the wall or ceiling rather than an integral part of the wall or ceiling (as devices moulded into a motor vehicle dashboard are integral in its form for example and are visually more satisfying to the human eye). A standard type of recessed light fitting has the disadvantage of drawing the users attention to the light fitting rather than to the area illuminated by the same fitting, especially when the exposed parts of the said fitting are of a different colour to the ceiling in which they are mounted. In general, most recessed or semi recessed light fittings available detract from the visual amenity of the architectural interiors in which they are used and very often make ceilings appear cluttered. When light fittings or other devices recessed into steel or timber framed walls or ceilings are larger than the distance between the framing elements that support the surface member (building board) of the same wall or ceiling, the same framing is normally modified to accommodate the fitting. This is generally labour intensive and requires more framing members than would otherwise be necessary. In buildings such as office towers the lighting systems, air conditioning duct work and other services are often installed above a suspended ceiling which is normally hung off a concrete slab. This has the advantage of requiring a framing system for the same ceiling, another system for the lighting, another system for the ductwork, hydraulic system and other services. All the systems are considered in isolation and then made to fit together generally between the said suspended ceiling and the concrete slab over. It is a crude and out dated way of installing services to a building.

These problems are overcome by the present invention, which provides a novel method of creating forms in standard wall or ceiling linings such as plasterboard, fibrous plaster, compressed fibrous cement, medium density fibre board and other fibre boards, cement render and set plaster as well as in concrete slabs or precast concrete systems. The said forms created may become and integral part of a utilitarian or decorative fitting, such as the housing and/or reflector of a light fitting. This is achieved by forming a step parallel to the outside edge of the said shaping member and perforating, segmenting, or otherwise forming an arrangement of penetrations and or incisions in the material of the said shaping member between the said step and the said outside edge (referred to in this document as the perforated fixing flange) in such a way that it can be covered with a settable filler material or standard jointing compound (usually plaster based and referred to in this document as a settable compound or filler material) or cement render so as to create a smooth join between the present invention and the surface member of the same wall or ceiling. The rear face of the perforated edge of the present invention is designed to be fixed to the surface of the surface member such as a ceiling or wall lining into which the shaping member is to be installed preferably with screws, clouts or clips before the settable compound or cement render is applied.

The same effect may also be achieved by securing to the rear face of the said surface member a fixing flange which is formed into or attached to the shaping member in such a way that it protrudes proud of the exposed face of the same surface member when installed so as to facilitate the application of a settable compound to cover any gap between the same shaping member and the same surface member as well as to form a smooth and continuous surface between the two said members.

The said connection allows the exposed surface of the wall or ceiling lining to be continuous with the exposed surface of the present invention and therefore making the same connection almost unapparent to the human eye. The most exposed surface of the present invention can thus be painted the same colour as the wall or ceiling lining into which it is installed. As the shaping member forms part of the ceiling or wall lining it can be said that the same wall or ceiling lining, due to the present invention, may be shaped to form part of a light fitting designed in accordance with the present invention which is a feature that is both visually satisfying to the human eye and in the case of recessed ceiling fittings, produces a low level of glare from the said light fitting. The same ceiling or wall so formed by this component of the said light fitting also has the duel function of acting as the reflector of the light fitting or as an additional reflector for the light fitting and therefore resulting in an economy of means.

As with the connection of all said shaping members with the said settable compound a fine line may be apparent at the edge of the said shaping member depending on the way the settable compound was applied and sanded. If it is preferable that no said fine line is apparent after having been painted, additional settable compound may be applied to the line and sanded after drying and additional coats of paint may be applied and sanded between coats after drying.

Another aspect of the present invention relates to the provision of supporting members integral to the present invention and applicable when the same invention is wider or longer than the distance between the framing members supporting the said surface member (such as plaster board) and thus the surface member will not be strong enough to support the present invention which will need to be supported by means of suspension rods or framing members or the like. In this case a different method of construction is employed in which the present invention is secured in its final position before the surface member is fixed in position. The framing members supporting the said surface member must also be in position prior to the installation of the same surface member. The same surface member is fixed to the support members integral to the present invention and to the said framing members. The present invention thus has the additional function of supporting the said surface member in a similar manner to the way the same surface member is supported by the said framing members.

Also, other advantage of the present invention when used as a structural support member for the said surface member of a ceiling is that several units of the same invention may be installed in a variety of orientations within the one installation while maintaining a consistent direction for the general ceiling framing.

When the said shaping member is used as a component of a recessed light fitting the visual impact of the same light fitting when installed is subtle and attention is drawn to the area illuminated rather than to the said fitting itself. The visual impact of the same light fitting when not in use is aesthetically appealing and adds to the visual amenity of the architectural interior wherein installed.

One method of joining the present invention to ceiling or wall linings has similarities to the method used to create straight and durable corners in plasterboard walls lining in which a perforated length of metal (called a setting bead) with a cross section in the approximate shape of a right angle, is secured with screws or clouts to the external corners of plasterboard lined walls commonly used in architectural applications. In this case the setting bead is completely covered with a plaster-based settable compound, which adheres to the plasterboard wall and the setting bead.

The perforations in the setting bead facilitate adhesion to the jointing compound and to the wall or ceiling lining. The setting bead is normally completely covered with jointing compound (settable material) that is easily sanded to provide a smooth finish. Tradesmen are accustomed to this method of construction and the same skills can therefore be easily applied to the said shaping members.

In one form of the invention the shaping member will be seen at the said junction, when installed, to be continuous with the surrounding wall or ceiling surfaces to which it is connected. This is made possible by the configuration of the edge of the said shaping member which comprise a perforated edge, which can be of varying width and stepped down along its length in direction toward the surface to which it is connected and thereby facilitating the application of the jointing compound or cement render. The application of the said jointing compound or said cement render may be completed with the use of a steel trowel or other device preferably with a straight edge, the edge of which may be dragged along the edge of the said step along the perforated edge strip of the said shaping member whilst remaining in contact with the surface of the same surface member during the operation. The settable material (jointing compound) or cement render would thus fill the perforations in the edge strip of the shaping member and ensure good bonding between the same shaping member and the surrounding surface member. The surface of the said shaping member, which is finished in line with the surrounding surfaces by virtue of the above procedure, may be formed into a shape necessary to contain or support or otherwise be attached to the other elements of the same device (such as a lamp holder for example).

In another form of the invention, where the said shaping member is fixed to the rear face of the said surface member, the shaping member will be seen, when installed, to be continuous with the surrounding surface member, such as wall or ceiling surfaces, to which it is connected. This is made possible by the configuration of the said shaping member, which is shaped so as to protrude proud (herein after the exposed corner of which shall be called a proud protrusion) of the face of the surface member in such a way that the application of the said jointing compound or said cement render may be completed with the use of a steel trowel or other device preferably with a straight edge, the edge of which may be dragged along the part of the said shaping member protruding proud (called the proud protrusion) of the said shaping member whilst remaining in contact with the surface of the same surface member during the operation. The settable compound (jointing compound) would thus fill the gap between the edge of the shaping member and the adjoining surface member and also cover the surface of the same surface member surrounding the joint with the said shaping member and form a preferably smooth and continuous surface between the two said members. In order to ensure good bonding between the same shaping member and the surrounding surface member screws or other fixing devices should preferably used to securely connect the same surface member with the same shaping member. When used with a cement render surface member, the cement render should preferably be applied to the substrate and be in line and in contact with the same proud protrusion in the same shaping member. The surface of the said shaping member, which is finished in line with the surrounding surfaces by virtue of the above procedure, may be formed into a shape necessary to contain or support or otherwise be attached to the other elements of the same device (such as a lamp holder for example).

In another form of the invention, the edge of the step of the said perforated edge, otherwise known as the proud protrusion, may be formed into a curved surface of very small radius (for example 1 mm) in order to allow the surface of the surface and shaping members such as a wall or ceiling lining to change planar direction at a relatively sharp angle (for example 90 degrees) at the junction of the said shaping member with the jointing compound applied to the surface member (the same shaping member may form the reflector and/or housing to a light fitting for example). This type of small radius junction not only allows for a different aesthetic as described in the first form of the invention described above but also allows for the fitting of a light diffuser or other member that may be positioned in line with the surface of the said wall or ceiling thus allowing for an elegant aesthetic. The said diffuser or other member would therefore appear as an inlay in the surface of the wall or ceiling thus reducing the visual impact of the said light fitting in terms of the number of components exposed to view. Also, the shaping member may form the reflector and housing for the light fitting.

In another form of the invention incorporating the same small radius junction as described above, a light diffuser can also be positioned so as to be recessed into the said wall or ceiling surface at a distance from the same junction and thereby further reducing glair and directing the light output onto a smaller area.

In another form of the invention with the same small radius junction, a diffuser may be formed so as to project beyond the surface of the said wall or ceiling in a curved or angular shape so as to allow the light to be diffused over a greater area than the previously described forms of the invention.

In another form of the invention with a small radius junction described above, a rectilinear shape may be formed in the said surface member in such an manner that a concave diffuser may be positioned behind the opening so created by the same small radius junction type shaping member and sit entirely within the same shaping member along with the lamp(s) and electrical gear and so configured to allow the entire face of the diffuser to be illuminated.

In another form of the invention and applicable to all of the forms of the invention described in this document which incorporate the said perforated edge strip type fixing flange and are circular when viewed looking toward the exposed face (with the exception of shaping members designed to act as structural support members herein described), L-shaped cleats may be formed into or attached to the said perforated edge of the said shaping member in such a manner that when they are inserted into a suitably shaped cut out in the said building board type surface members, the same shaping member may be rotated in such a manner that the L-shaped cleats overlap the same shaping member, allowing for the insertion of screws into designated holes in the said perforated edge to be drilled through the same surface member into the same L-shaped cleat. The same L-shaped cleat ensures that the same surface member is thoroughly secured relative to the said shaping member and therefore any differential movement, such as that caused by thermal expansion and contraction of the surface member relative to the shaping member, will be constrained, preventing cracking of the said filler material (settable compound), within normal operating conditions.

In another form of the invention and applicable to all of the forms of the invention described in this document incorporating the said perforated edge strip (with the exception of the form of the invention in which the said shaping members designed to act as structural support members herein described and also the form of the invention incorporating L-shaped cleats), spring metal cleats may be attached to the said perforated edge strip of the said shaping member in such a manner that when they are inserted into a suitably shaped cut out in the said building board type shaping members, the same spring metal cleats will deform during insertion and resume their original shape in such a manner that spring metal cleats overlap the same shaping member, allowing for the insertion of screws into designated holes in the said perforated edge to be drilled through the same surface member into a perforation in the same spring metal cleats. The same spring metal cleats ensures that the same surface member is thoroughly secured relative to the said shaping member and therefore any differential movement caused by thermal expansion and contraction of the same surface member relative to the same shaping member will be constrained, preventing cracking of the said filler material, within normal operating conditions.

In another form of the invention and applicable to all of the forms of the invention described in this document incorporating the said perforated edge strip (with the exception of the form of the invention in which the said shaping members designed to act as structural support members herein described and also the form of the invention incorporating L-shaped cleats and spring metal cleats), L-shaped, pivoting bracket may be attached to the said perforated edge of the said shaping member in such a manner that when they are inserted into a suitably shaped cut out in the said building board type surface members, the same L-shaped, pivoting bracket may be rotated with a screw driver or other tool in such a manner that L-shaped, pivoting bracket overlaps the same surface member, allowing for the insertion of a screw into the designated holes in the said perforated edge to be drilled through the same surface member into a perforation the same L-shaped, pivoting bracket. The same L-shaped, pivoting bracket ensures that the same surface member is thoroughly secured relative to the said shaping member and therefore any differential movement caused by thermal expansion and contraction of the same surface member relative to the same shaping member will be constrained, preventing cracking of the said filler, within normal operating conditions.

In another form of the invention and applicable to all of the forms of the invention described in this document incorporating the said perforated edge strip (with the exception of the form of the invention in which the said shaping members designed to act as structural support members and also the form of the invention incorporating L-shaped cleats, spring metal cleats and L-shaped, pivoting brackets herein described), spring metal clips may be attached to the inside edge of the said perforated edge of the said shaping member in such a manner that when the present invention is inserted into a suitably shaped cut out in the said building board type shaping members, the same spring metal clips will deform during insertion and resume their original shape in such a manner that spring metal clips put force on the same shaping member in order to hold the said shaping member still relative to the same surface member. The edge and the surrounding surfaces of the said cut out are preferably to be covered with suitable adhesive before insertion of the present form of the invention into the said cut out. The same spring metal clips ensures that the same adhesive is allowed to dry in a manner such that the surface member is thoroughly adhered to the said shaping member and therefore any differential movement caused by thermal expansion and contraction of the same surface member relative to the same shaping member will be constrained, preventing cracking of the said filler material, within normal operating conditions. The same spring metal clip may be attached to a cleat formed from the same shaping member with the advantage that fixing components such as rivets will not interfere or protrude into with the same surface member.

Note that standard filler material alone may prevent differential movement over the normal life of the invention if the said shaping member is relatively small. If the form of the invention is very small, the cracking in the said filler material due to differential movement may be so fine so as not to be apparent to the human eye especially when pained and is therefore an acceptable form of the invention.

In another form of the invention and applicable to all of the forms of the invention described in this document, it may be necessary to accommodate differential movement between the said light fitting and the surrounding wall or ceiling surfaces to which it is joined if the size of the said light fitting is large enough to warrant the consideration of such differential movement. If the accommodation of the said differential movement is warranted, special joints (to be referred to as “slip joints” in this document) may become necessary to allow for movement between the part(s) of the shaping member that is joined to the surface member and the main body of the device in question such as a light fitting. One form of slip joint that may be incorporated in the present invention may comprise elongated openings in the main body of the same device into which is inserted metal pins, studs or threaded studs (for use with fastening nuts) attached to the shaping member that is connected to the surface member. The slip joint may be a similar system that would allow for the main body of the light fitting to expand or contract independently of the ceiling or the wall within a limited range of movement.

Adhering an elastic or flexible strip between the said shaping member and the body of the device in question may form another form of the said slip joint described above.

In this preferred form of the invention, the shaping member may be made of any suitable material, such as metal, moulded plastic, fibre cement or compressed fibre cement.

Also preferably, the perforations in the strip along the perforated edge (referred to in this document as the perforated fixing flange), designed to connect to the said surface member, may be made in various suitable shapes and sizes. The same perforated edge may also be segmented and/or have any variety of incisions or a combination of perforations and notches.

Preferably, the shaping member is formed of a material that is relatively thin compared to the surface member and strong in tension so that the penetration of the fixing devices such as self-tapping screws is facilitated. Fibre reinforced cast plaster is not an acceptable material for the current invention.

In a preferred embodiment, the said fitting is a light fitting, such as a dome with electrical gear, lamp and diffuser contained within the same dome, the body of the dome acting as the ceiling lining, the reflector and the housing, in part, for the same light fitting.

Also, in another form of the invention, the said shaping member may form the lighting pelmet surrounding the perimeter for a dome for use in a ceiling, the same pelmet forming an upturn in the same ceiling surface member and, as seen in plan view, be formed as a circle, oval, oblong or other shape with lighting device(s) fitted within the same pelmet to provide light to the said dome mounted above and enclosing the said pelmet.

In another form of the invention the said fitting is a light fitting formed into a rectilinear shape wherein it can be said that the fitting shapes the said surface member to form not only the housing and reflector of the said light fitting but also the support means of the diffuser. This may be achieved by forming ledges within either side of the said body of the said fitting upon which a light diffuser may rest. Electrical gear may be positioned within the same housing or located remotely from the same fitting. Perforations may be made within the same reflector/housing to secure lamps, enable cable entries and provide for support structures.

In another form of the invention the said fitting is a light fitting formed into a recessed light fitting wherein it can be said that the fitting shapes the said surface member into a concave shape to form the housing and reflector of the said light fitting within which the electrical gear(s), lamp(s) and, if necessary, light diffusers are housed.

In another form of the invention the said fitting is a light fitting that shapes part of the wall or ceiling lining to form a convex protrusion in the same surface member and may preferably accommodate electrical gear(s), lamp(s) and diffuser(s).

A another aspect of the present invention and applicable to all of the forms of the invention described in this document, and depending on the size of the present invention, the present invention may form a structural member, when supported from other structural elements, capable of providing support to the said surface member and thereby facilitating installation and reducing the number of structural elements needed to support the said surface member (assuming that the surface member is a building board type member).

In alternatively preferred embodiments the said shaping member may form part of any type of vent such as an air conditioning outlet, a sprinkler, or any other fitting normally used in conjunction with and architectural elements including walls, ceilings or eaves linings.

In a broad form, one aspect of the present invention provides a method of forming shapes integral with the said surface member, which comprises the steps of:

-   -   Cutting or preparing an opening in the said surface member.     -   Covering the edge and surrounding surfaces in the proximity of         the same opening with adhesive suitable to bond the said surface         member with the said shaping member if necessary.     -   Inserting and attaching (using constraining said spring metal         clips plus adhesive, said spring metal cleats, said pivoting         plastic cleats plus adhesive, said L-shaped cleats plus         adhesive, other forms of cleat, clip, attachment device plus         adhesive or adhesive only) the said shaping member within or         about the said opening (the said shaping member has a flat         perforated strip along its outside edge with a step along the         side of the said perforated edge strip closest to the body of         the said shaping member) in a manner whereby the inside surface         of the said perforated edge is attached to the said surface         member around and in line with the said opening and so that the         same adhesive applied to the same opening is well connected to         the said shaping member; and, after the said adhesive has set,         providing a layer of settable material over the said perforated         edge to the said step along the same perforated edge.         Preferably, said shaping member is formed into any desired shape         and becomes a continuation of the said surface member. Also the         opening is formed of any desired shape, and upon which a shaping         member may be attached normally of corresponding shape to the         opening.

Also preferably the said surface member is plasterboard, plaster, fibre cement, fibre reinforced board or a rendered surface, wherein the said settable material includes plaster render, standard jointing compound (commonly available on the market) or other filler material.

In the another aspect of the present invention the said fitting is a light fitting of other device with an elongated rectilinear or curvilinear opening with a length that exceeds the distance between the framing elements supporting the surface member such as a standard plasterboard or fibre cement ceiling lining. In this form of the invention, the said fitting may be used to not only shape the ceiling and form a reflector/housing or other form but also to provide support for plasterboard or fibre cement surface members where the same surface member is attached to the said perforated edge of the same fitting. This is achieved with the incorporation of a flange attached to the housing of the same fitting and positioned an appropriate distance from the said perforated edge so as to allow the surface member (if plasterboard or fibre cement) to be inserted between the two said members and screw fixed in position before adhesive and any said filler material is applied.

Another aspect of the present invention provides a method of forming elongated or relatively large shapes within the said surface member, which comprises the steps of:

-   -   Suspending the said shaping member preferably from adjustable         suspension rods or support member so as to position the         perforated fixing flange of the same shaping member to be in         line with the exposed face of surface member.     -   Inserting and attaching the said plasterboard, fibre cement         sheet or other building board like surface member between the         said perforated fixing flange and the clamping flange attached         to the shaping member and screw fixing the same surface member         to standard ceiling framing appropriately positioned.     -   Screwing self tapping screws through the same perforated fixing         flange and the said surface member, into the same clamping         flange attached to the shaping member;         and, providing a layer of settable material over the said         perforated edge to the said step along the same perforated edge.         Preferably, such housing (shaping member) is formed into a         rectilinear shape and becomes a continuation of the said surface         member suitable to house, for example, electrical gear and lamp         as well as act as a reflector.

Also preferably the shape formed may appear as a rectilinear slot in the said surface member (ceiling), the inside face of which may be painted the same colour as the rest of the same ceiling. Light diffusers may also be incorporated and positioned in line with the surface member, recessed in from the surface member or protruding out from the face of the surface member and lighting devices including electrical gear may be housed within the same shaping member formed into the said rectilinear slot or may be housed in an ancillary housing.

Also in another form of the invention the said shaping member may form an elongated shape within the said ceiling surface member, one side of which forming an upturned lighting pelmet, the other side forming a shape that envelopes the same upturned pelmet in such a manner as to form a reflector for lighting devices housed within the same pelmet, which is designed to reflect light from the same lighting devices so that all the light emanating from the present form of the invention is reflected and not directly emanating from the same lighting devices when viewed from the space which it was designed to illuminate. This same form of the present invention may also be positioned within the said surface member of a wall.

Also preferably the shaping member may be curvilinear in plan along its extremities, the said perforated edge extending over two or more framing members, and may be formed into a dome of circular, elliptical or other shape in plan and be capable of acting as a supporting member for the surrounding surface member when the shaping member's structural strength is adequate. If the same design is applied to the said surface member when used in a wall, however, suspension rods would normally not be appropriate as the said fitting may be secured with the use of standard framing members, however the same flange/perforated edge configuration described above is applied and thereby negates the need for framing members in the wall to the entire perimeter of the shape formed by the shaping member.

An added advantage of the above configuration of the present invention, utilising the said clamping flange into which to fix the said surface member to the said perforated edge, is that the same surface member is thoroughly secured relative to the said shaping member and therefore any differential movement caused by thermal expansion and contraction of the surface member relative to the shaping member will be constrained, preventing cracking of the said filler material by constraining any potential differential movement within the fabric of the surrounding members and thereby causing internal stresses and tensions within the same fabric, which is manageable within a range of limits however when this same range of limits is exceeded, the said slip joints need be applied.

The said aspect of the present invention incorporating the said settable proud protrusion described in this document provides a method of forming elongated or relatively large shapes within the said surface member, which comprises the steps of:

-   -   Suspending the said fitting from adjustable suspension rods so         as to position the settable proud protrusion of the same shaping         member so as to be in line with the intended exposed face of         surface member.     -   Attaching the said surface member (such as plasterboard, fibre         cement sheet or other board like surface member) to the fixing         flange of the shaping member and screw fixing the same surface         member to standard ceiling framing appropriately positioned.     -   Screwing self tapping screws or other fixing devices through the         same surface member, into the said fixing flange of the shaping         member and, providing a layer of settable compound to the face         of the surface member near the perimeter of the exposed portion         of the shaping member to the proud protrusion.

Preferably, said shaping member (housing) is formed into a rectilinear shape and becomes a continuation of the said surface member suitable to house, for example, electrical gear and lamp as well as act as a reflector.

Also, another advantage of the present invention when used as a structural support member for the said surface member of ceiling system that is suspended from other structural members is that the inherent rigidity of the same invention may also be employed to support general (primary) framing members of the same ceiling system;

-   and may be achieved with the use of cleats, angles, brackets and the     like or suitable shapes formed into the body of the same invention     onto which may be fixed framing members which abut the same     invention to which secondary framing members such as furring battens     or channels may be attached, which is turn may be directly fixed to     the said surface member; -   and a structural system may also be configured by employing a     repetition of the present form of the invention within a single     ceiling as one or more said primary framing members may span between     numbers of the same invention and thus be well positioned to support     secondary framing members (such as furring channels or battens) from     which the same surface member may be suspended as well being     suspended from the present invention along the line of abutment of     the same surface member with the fixing flange of the same     invention.

The said aspect of the present invention described above provides a method of forming structural framing members integral to the said shaping member as well as shaping the same surface member to facilitate utilitarian devices and/or add decorative elements, which comprises the steps of:

-   -   Suspending the said fitting from adjustable suspension rods so         as to position the perforated edge strip of the same fitting to         be in line with the intended exposed face of surface member.     -   Supporting framing members of a ceiling system (which are also         supported or suspended from other structural members of a         building) from the said fitting with the use of cleats, angles,         channels, brackets or the like attached or formed into the same         fitting.     -   Attaching structural suspension members from structural members         in order to support the said framing members if the span between         the said fittings or the span from the same fittings to an         adjoining structural support members (such as a wall) is greater         than can be born by the same framing member.     -   Attaching framing members such as furring battens, channels or         the like to the same framing members so that the distance         between the same furring members is no greater than the distance         that the said surface member can span and so that the same         furring framing members are in line with the said flange of the         said fitting.     -   Inserting and attaching the said surface member (such as         plasterboard, fibre cement sheet or other building board like         surface member) between the said perforated edge strip and the         said flange attached to the housing of the said fitting and         screw fixing the same surface member to said furring framing         members appropriately positioned.     -   Screwing self tapping screws through the same perforated edge         and the said surface member, into the same flange attached to         the said fitting; and, providing a layer of settable material         over the said perforated edge to the said step along the same         perforated edge.

The said aspect of the present invention, which incorporates the said settable proud protrusion, provides a method of forming structural framing members integral to the said shaping member as well as shaping the same surface member to facilitate utilitarian devices and/or add decorative elements, which comprises the steps of:

-   -   Suspending the said fitting from adjustable suspension rods so         as to position the said settable proud protrusion of the same         fitting to be in line with the intended exposed face of surface         member.     -   Supporting framing members of a ceiling system (which are also         supported or suspended from other structural members of an         architectural work) from the said fitting with the use of         cleats, angles, channels, brackets or the like attached or         formed into the same fitting.     -   Attaching structural suspension members to structural members in         order to support the said framing members if the span between         the said fittings or the span from the same fittings to an         adjoining structural support members (such as a wall) is greater         than can be born by the same framing member.     -   Attaching framing members such as furring battens, channels or         the like to the same framing members so that the distance         between the same furring members is no greater than the distance         that the said surface member can span and so that the same         furring framing members are level with the said flange of the         said fitting.     -   Attaching the said surface member (such as plasterboard, fibre         cement sheet or other building board like surface member) to the         said fixing flange of the said shaping member with the use of         self-tapping screws or other fixing devices.     -   Providing a layer of settable compound from the said proud         protrusion to the face of surface member in the proximity of the         shaping member.

In another form of the present invention and when the said shaping member is required in longer lengths than is practical or economical to supply and/or transport, it may be necessary to join two lengths of the same shaping member in a manner that the joint between the abutting said shaping members is not normally apparent when viewed by the human eye. This may be achieved with the use of perforated edges along the line of the joint between the two said shaping members, which may be stepped back from the face of the said shaping member allowing for the application of said filler material and also to prevent movement between the two said abutting shaping members, one of the two abutting said perforated edges may incorporate a second step back from the face of the same shaping member to allow for a lap between the two said perforated edges which may be fixed together with the use of screws or other mechanical fixing devices and/or adhesive prior to the application of the said filler material.

In another form of the invention, the said shaping members may be used to join different materials. For example, a cement rendered wall may be connected with a plasterboard ceiling with a said shaping member in the shape of a cove which also may be used with a light fitting utilising the cove as a reflector.

An economy of means in terms of the structural system of the overall construction is achieved by the present invention. Using the inherent rigidity of the present invention for employment as a structural element is a unique feature of the present invention when it is suspended or otherwise supported from other, more major, structural members and it can therefore be said that the present invention may be used to support the said surface member in conjunction with the said general framing members.

DESCRIPTION OF PREFERRED EMBODIMENTS

To assist with the understanding of the invention, reference will now be made to the accompanying drawings, which show examples of the invention. The said examples are of a preferred but non-limiting embodiment

Throughout the drawings, like numerals will be used to identify similar features, except where expressly otherwise indicated.

Wall lining or ceiling lining in this document normally refers to the combination of the surface member 7 and the shaping member 1, which are connected according to this invention so that no joint is apparent and therefore visually forming one continuous surface, be it of differing materials. This is made possible by the aspect of the invention that constrains any differential movement between the same differing materials.

In the drawings:

FIG. 1 shows one example of a shaping member 1(ex), which is flush joinable to surface members (including wall surfaces) and designed to provide a rounded corner according to this invention. It is shown in section across its length and in this case it is in the form of a setting bead for external (270 degree) corners in preferably plasterboard lined walls (plasterboard being the said surface member in this case). As well as shaping the corner it provides a durable straight edge. It is preferably made out of metal such as steel or aluminium or may be made of PVC or some form of durable and suitably hard plastic. Preferably if should be manufactured in lengths that are long enough to be fitted in one length in most applications, but however may be butt joined for very long runs.

NB. Setting beads currently available are normally used in to form straight and durable eternal corners and are installed after the surface members are fixed into position.

FIG. 2 shows the same shaping member in elevation according to this invention.

FIG. 4. shows the same shaping member 1(ex) as in FIG. 1 in plan view when installed vertically into the external corner junction of two walls.

To install, fix setting bead 1(ex) to framing 6 with screws 3 or other fixing devices or techniques before installing the surface member 7 (plasterboard in this case). Install the surface member 7 so that it butts up against the setting bead shaping member 1(ex). Fix with screw 3 or secure by other means the surface member 7 to the fixing flange 4 of the setting bead shaping member 1(ex) so as to ensure a firm connection and prevent any visible movement between the two members. Apply settable compound 2 to the junction between the setting bead 1(ex) and the surface member 7 to provide a smooth and even surface between the two members. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusion 5 and the surface of the surface member 7. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

In this form of the invention and for all forms of the invention designed for use as a setting bead, the fixing flange 4 of the shaping member 1(ex) and 1(in) is securely fixed to the framing member 6 as well as to the surface member 7 and is designed to prevent differential movement between the same shaping member 1(ex) and 1(in), the same framing member 6 and the same surface member 7.

It will be realized that all the setting bead type shaping members according to this invention is not restricted to any shape and the shape may change along its length. For example the profile of any setting bead type shaping member according to this invention may form a right angle edge at its base to accommodate skirting boards and the like, form into a rounded corner along its length and form into a right angle edge at the top to accommodate cornices and the like. This may be achieved with joinable lengths or with one length, which may be trimmed before instillation if necessary.

FIG. 3 shows an example of a shaping member 1(in), which is flush joinable to surface members 7 (including plasterboard wall and ceiling surfaces) and designed to provide a rounded corner according to this invention. It is shown in section across its length and in this case it is in the form of a setting bead for internal (90 degree) corners in which preferably plasterboard lined walls are the said surface member 7. As well as shaping the corner it provides a durable straight edge. It is preferably made out of metal such as steel or aluminium or may be made of PVC or some form of durable and suitably hard plastic. Preferably if should be manufactured in lengths that are long enough to be fitted in one length in most applications, but however may be joined end to end for very long runs.

Fix in position with screw 3 or secure by other means the surface member 7 to the fixing flange 4 of the setting bead shaping member 1(in) so as to ensure a firm connection and prevent any visible movement between the two members. Apply settable compound 2 to the junction between the setting bead and the surface member to provide a smooth and even surface between the two members. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusion 5 and the surface of the surface member 7. If necessary sand the setting compound after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish.

FIG. 5 shows an example of a shaping member 1(ex), which is flush joinable to surface members 7 (including wall and ceiling surfaces) according to this invention and embodies the same purpose and method of installation as FIG. 1 with the exception that the shaping member embodied in FIG. 5 provides for a relatively sharp edged corner.

In order to facilitate good bonding between the shaping member 1(ex) and the surface member 7 reinforcing 12 is provided which is preferably mesh or paper which is to be installed so as to be fully surrounded by the settable compound 2 where it is in contact with the surface member 7. The said reinforcing is to be such that if there is any minor cracking in the settable compound 2, after setting, the reinforcing will ensure that the cracks will be so minute so as to be unapparent to the human eye especially after a paint finish is applied. Preferably the reinforcing 12, when made of paper, may cover the entire surface of the setting bead exposed to view when installed.

FIG. 25 shows one example of a shaping member 1(in), which is flush joinable to surface members (including wall surfaces) and designed to provide a rounded corner according to this invention. It is shown in cross section and in this case it is in the form of a setting bead for internal (90 degree) corners in preferably plasterboard lined walls as the said surface member 7.

FIG. 26. shows the same shaping member—1(ex) as in FIG. 24 and 1(in) as in FIG. 25—in plan view when installed vertically into the corner junctions of two walls.

To install, fix setting bead shaping members 1(ex) and 1(in) to framing 6 with screws 3 or other fixing devices or techniques before installing the surface member 7. Install the surface members 7 so that it is positioned between the fixing flange 4 and the reinforcing 12 and pushed up against the setting bead shaping members 1(ex) and 1(in). Fix in position with screws 3 or secure by other means the surface member 7 to the fixing flange 4 of the setting bead shaping member 1(ex) & 1(in) so as to ensure a firm connection and prevent any visible movement between the two members. Apply settable compound 2 between the proud protrusion 5 and the surface member 7 and embed the reinforcing 12 into the same settable compound 2 and if required apply more settable compound 2 to fully cover the reinforcing 12 and to provide a smooth and even surface between the proud protrusions 5 of the shaping members 1(ex) & 1(in) and the surface of the surface member 7. If necessary sand the setting compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish.

FIG. 27 shows an example, as a three dimensional representation, of a shaping member according to this invention.

FIG. 28 shows the application of such a shaping device, as a two dimensional cross sectional representation, when installed into the edge of a plasterboard ceiling. The same invention may also be installed vertically preferably at the junction of two walls or horizontally, preferably to the top of a wall, at the junction with the ceiling.

Referring to FIG. 27 it can be seen that the shaping member according to this invention comprises an elongated member, which is “T” shape in cross section and is of indefinite length. The part of the said invention, which is used to fix the same invention to framing 6 or structural members as well as to lining members 7 is referred to as the fixing flange 4. It is normally for use in shaping a surface member 7 such as plasterboard in such a way as to form a small gap (commonly known in the building industry as a ‘shadow line’) at the junction of one surface member 7 with another surface member 7, which are preferably at right angels to each other.

FIG. 28 shows the shaping device in operation. It can be seen that the ceiling is lined with a building board type surface member 7, preferably plasterboard, which is attached to ceiling framing 6. It can also be seen that the wall is lined with a building board type surface member 7, attached to wall framing 6, shown as the vertical lines adjacent to the shaping member 1.

This devise allows the surface member (in this case the ceiling lining) to be neatly finished in a straight line with a durable edge, which is preferably in line with and close to an adjacent wall. It provides an aesthetically appealing finish and makes cracking at the junction where it abuts the wall difficult to detect.

To install, fix shaping member 1 to framing 6 with screws 3 or other fixing devices or techniques before installing the surface member 7 (plasterboard in this case). Install the surface member 7 so that it butts up against the setting bead shaping member 1.

Fix with screw 3 or secure by other means the surface member 7 to the fixing flange 4 of the shaping member 1 so as to ensure a firm connection and prevent any visible movement between the two members. Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusion 5 and the surface of the surface member 7. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

It will be realized that the shaping member according to this invention is not restricted to the form of a “T” shape (in cross section) setting bead. It may be incorporated with a bendable locking flange 9, a wedging flange 10 and reinforcing 12.

FIG. 29 shows an example, as a three dimensional representation, of a shaping member according to this invention.

FIG. 31 shows the application of such a shaping device, as a two dimensional cross sectional representation, when installed into the perimeter of a plasterboard ceiling.

The same invention may also be installed vertically preferably at the junction of two walls or horizontally, preferably to the top of a wall, at the junction with the ceiling.

FIG. 30 shows a more detail view of the shaping member 1 in FIG. 31.

Referring to FIG. 29 it can be seen that the shaping member according to this invention comprises an elongated member of indefinite length. The part of the said invention, which is used to fix the same invention to framing 6 or structural members as well as to surface members 7 is referred to as the fixing flange 4. It is normally for use in shaping a surface member 7 such as plasterboard in such a way as to form a small gap at the junction of one surface member 7 with another surface member 7, which are preferably at right angels to each other. The same shaping member also forms an enclosure to house a light source 13, which is preferably in the form of a series of light emitting diodes (LEDs) configured in a strip form and used to illuminate the gap so formed by the said shaping member 1.

FIG. 31 and FIG. 30 shows the shaping member 1 according to this invention in operation. It can be seen that the ceiling is lined with a building board type surface member 7, preferably plasterboard, which is attached to ceiling framing 6. It can also be seen that the wall is lined with a building board type surface member 7, attached to wall framing 6, shown as the vertical lines adjacent to the shaping member 1.

This devise allows the surface member (in this case the ceiling lining) to be neatly finished in a straight line with a durable edge, which is preferably in line with and close to an adjacent wall. It provides an aesthetically appealing finish and makes cracking at the junction where it is applied difficult to detect as well as providing an enclosure for a light source.

To install, fix shaping member 1 to framing 6 with screws 3 or other fixing devices or techniques before installing the surface member 7 (plasterboard in this case). Install the surface member 7 so that it butts up against the setting bead shaping member 1.

The L-shaped fixing cleats 24 may be formed into or attached to the said perforated fixing flange 4 p of the said shaping member 1 in such a manner that when they are inserted into a suitably shaped cut out in the said building board type surface member 7, the same shaping member 1 may be rotated in such a manner that the L-shaped cleats overlap the same surface member 7, allowing for the insertion of screws 3 into designated aperture 25 in the said perforated fixing flange 4 p to be drilled through the same surface member 7 into the aperture 26 in the in the same L-shaped fixing cleat 24. The fixing method herein described incorporating the same L-shaped cleat 24 ensures that the same surface member 7 is thoroughly secured relative to the said shaping member 1 and therefore any differential movement caused by thermal expansion and contraction of the surface member relative to the shaping member will be constrained, preventing cracking of the filler material known as the settable compound 2 within normal operating conditions and within a range of sizes for the same invention.

Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members.

This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusion 5 and the surface of the surface member 7. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

Preferably install a suitable device such as lighting device 13 into opening 8 and secure appropriately.

FIG. 102 shows the application of such a shaping member 1 for creating shapes in the surface member 7 that facilitate the installation of a diffuser 15 as a cross sectional representation when installed into a plasterboard ceiling (plasterboard being the surface member 7).

Referring to FIG. 100, it can be seen that the shaping member according to this invention comprises a somewhat orthogonal member of indefinite size formed into a fixing flange 4, proud protrusion 5 as well as the main body of the shaping member 1. The part of the said invention, which is used to fix the same invention to the surface member 7, is referred to as the fixing flange 4. This form of the invention forms an opening in the surface member 7, which preferably may be used to support a light fitting or other utilitarian device or may be used for decorative purposes. The said opening is shaped so as to seat a removable hatch and the hatch may also double as a light fitting.

To install, preferably suspend the primary framing members 6 p along with shaping member 1 with the use of rods, threaded rods with bolts or other framing members or methods so the flange 4 is in line with the intended rear face of surface member 7.

Normally the device consisting of shaping members 1 and reflector 20 is installed before the primary framing members 6 p are suspended. Insert primary shaping member 6 p into support 21 during installation. Fix secondary framing members 6 to the underside of the primary framing members 6 p, ensuring that a secondary framing member 6 is positioned between the fixing flange 4 and the primary framing member 6 p along the length of the same fixing flange 4 in accordance with the drawings. Fix the surface member 7 to the fixing flange 4 of shaping member with screws 3. Other fixing devices or techniques may be used so as to ensure a firm connection and prevent any visible movement between the shaping member 1 and the surface member 7. Also fix the same surface member 7 to the faming members 6. Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members. In situations when two shaping members 1 are in close proximity as in FIG. 115 the settable compound 2 may be applied to the surface member 7 between adjacent proud protrusions 5. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the two adjacent proud protrusions 5. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

It can be said that, in this form of the invention, the shaping member 1, as well as shaping the surface member 7 7, also forms part of the structural support system for the same surface member 7 as well as for the primary framing member 6 p.

Preferably reflectors 20 in accordance with FIG. 115 may be removable allowing access to the area above the suspended ceiling.

Install the device consisting of shaping members 1 and reflector 20 to the soffit of the slab 19. Allow for a gap in the surface member 7 for the installation of the shaping members 1. Ensure that a framing member 6 is located between the perforated fixing flange 4 p and the underside of the slab 19 along the length of the perforated fixing flange 4 p. Fix the perforated fixing flange 4 p of shaping member 1 to the surface member 7 and to the framing member 6 with screws 3. Other fixing devices or techniques may be used so as to ensure a firm connection and prevent any visible movement between the shaping member 1 and the surface member 7. Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the two adjacent proud protrusions 5. Three applications of the said settable compound is normally needed to achieve a good finish when perforated fixing flange 4 p is used. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting. It will be realized that the shaping member according to this invention is not restricted to the form illustrated and may be used to form square, rectangular, oblong, curvilinear or any other shapes and the profile of the shaping members 1 and reflector 20 may be formed into any shape.

FIG. 118 shows an example, as a cross sectional representation, of a shaping member according to this invention intended for use as a light fitting.

FIG. 119 shows the application of such shaping members 1 for creating shapes in the ceiling lining (“lining” in this document refers to the combination of the surface member 7 and the shaping member 1) to facilitate the installation of a light source 13 and reflector 20 and is shown as a cross sectional representation when installed into a plasterboard ceiling (plasterboard being the surface member 7) using a framing system that consists of framing members 6 fixed primary framing members 6 p.

FIG. 119 shows the shaping device depicted in FIG. 118 in operation. It can be seen that the ceiling is lined with a building board type surface member 7, preferably plasterboard, which is attached to ceiling framing 6.

This devise allows the surface member 7 (in this case the plasterboard) to be joined with the shaping member 1 in such a way as to form a continuous part of the ceiling lining as no joint is apparent between the shaping member 1 and the surface member 7 when both surfaces are finished with the same paint finish.

To install, preferably fix the framing members 6 to primary framing members 6 p.

Also fix the same surface member 7 to the faming members 6. Allow for a gap in the surface member 7 for the installation of the shaping members 1. Fix the device consisting of shaping members 1 and reflector 20 to framing members 6 and 6 p.

Ensure that a framing member 6 is located between the fixing flange 4 and the underside of the slab 19 along the length of the fixing flange 4. Fix the fixing flange 4 of shaping member 1 to the rear face of surface member 7 and to the framing member 6 with screws 3. Other fixing devices or techniques may be used so as to ensure a firm connection and prevent any visible movement between the shaping member 1 and the surface member 7. Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusions 5 and the surface member 7. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

Preferably reflectors 20 in accordance with FIG. 115 may be removable allowing access to the area above the suspended ceiling.

FIG. 120, FIG. 121, FIG. 122, FIG. 123 and FIG. 124 shows examples, as a short cross sectional representation, of shaping members according to this invention.

FIG. 125 shows the application of such shaping members 1 for creating shapes in the ceiling lining (“lining” in this document refers to the combination of the surface member 7 and the shaping member 1) to facilitate the installation of a light source 13 and reflector 20 and is shown as a cross sectional representation when installed into a ceiling coated with a layer of plaster (plaster being the surface member 7) applied directly to the soffit of a reinforced concrete slab. The wall supporting the same slab on the left side is finished with layer of cement render and a second layer consisting of plaster to provide a hight quality finish which is standard practice when hight quality finishes are required. The perforated fixing flange in this form of the invention is designed to accommodate both cement render and plaster finishes. The wall on the right side of the figure is finished with cement render only and the perforated fixing flange is designed to accommodate the one layer of cement render as is commonly used in architectural applications.

Referring to FIG. 120, FIG. 121, FIG. 122, FIG. 123 and FIG. 124, it can be seen that the shaping member 1 has a perforated fixing flange 4 p or 4 r+p about its perimeter, which may be fixed the surface member of render, plaster or render finished with plaster. FIG. 122 shows an enlarged view of the fixing flange 4 r+p as indicated by the circles joined with a line. FIG. 121 shows an enlarged view of the fixing flange 4 p as indicated by the circles joined with a line.

FIG. 125 shows the shaping devices depicted in FIG. 120, FIG. 121, FIG. 122, FIG. 123 and FIG. 124 in operation.

FIG. 126 shows an enlarged view of FIG. 121 (the connection between the surface member 7 p and the perforated fixing flange 4 p of the shaping member 1) in operation as indicated by the circles joined with a line.

It can be seen that in this example the ceiling is lined with an applied plaster type surface member 7 p, commonly referred to as hard plaster finish or set plaster, which is applied to walls or ceilings when wet (that is in a plastic state with a high water content prior to setting).

The devise in FIG. 121 and FIG. 126 allows the surface member 7 p (in this case applied plaster) to be joined with the shaping member 1 in such a way as to form a continuous part of the ceiling lining so as no joint is apparent between the shaping member 1 and the surface member 7 when both surfaces are finished with the same paint finish.

To install, preferably fix shaping member 1 with the use screws 3, or other appropriate fixing devices so that fixing flange 4 p is in line with the intended soffit of slab 19. Other fixing techniques may be used so as to ensure a firm connection and prevent any visible movement between the shaping member 1 and the slab 19.

Normally the device consisting of shaping members 1 and reflector 20 is installed before the surface member 7 p is applied. Apply the surface member 7 p to the soffit of the slab 19 and level with and in contact with the proud protrusion 5, covering the perforated fixing flange 4 p of shaping member. In situations when two shaping members 1 are in close proximity, as in FIG. 125, the surface member 7 p may be 45 applied to the between adjacent proud protrusions 5. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the two adjacent proud protrusions 5. Ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

The devise in FIG. 122 and shown in operation in FIG. 125 allows cement render with an applied plaster type surface member 7 p to be joined with the shaping member 1 in such a way as to form a continuous part of the wall lining so as no joint is apparent between the shaping member 1 and the surface member 7 when both surfaces are finished with the same paint finish.

To install apply cement render to the wall 18 so that it is finished in line with and covering the perforated fixing flange 4 r+p. After the same cement render sets and reaches an appropriate moisture content, apply the surface member 7 p so that it is in line with the proud protrusion 5 and parallel with the wall 18. Ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

It can be seen on the right side of FIG. 125 that the shaping member 1 is joined to a surface member 7 which is, in this case, a layer of cement render without a covering coat of plaster. The perforated fixing flange 4 r is used in this situation as it does not employ a step as seen in fixing flange 4 r+p which is intended preferably for use with an applied plaster finish 7 p. To install apply cement render 7 r to the wall 18 so that it is finished in line with and covering the perforated fixing flange 4 r. Ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting apart from a change in texture between the shaping member 1 and the surface member 7 r. It will be realized that the shaping member according to this invention is not restricted to the form illustrated and may be used to form rectilinear, oblong, curvilinear or any other shapes.

The junction with the ceiling follows the same principles as described in FIG. 113 and therefore shall not be repeated. The junction of the shaping member 1 with the wall shall be described following.

Referring to FIG. 127 and FIG. 129, it can be seen that the shaping member 1 according to this invention comprises a device of indefinite size and shape. The part of the said invention, which is used to fix the same invention to the surface member 7 is referred to as the fixing flange 4, which, in this form of the invention, normally may only be used on two sides of the shaping member 1 as it may run the entire length of the room or space into which it is installed.

This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the proud protrusion 5 and the surface of the surface member 7. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting. It will be realized that the shaping member according to this invention is not restricted to the form illustrated. It may also be incorporated with reinforcing 12 as may all forms of this invention.

FIG. 133 shows examples, as a short cross sectional representation, of shaping members according to this invention.

FIG. 134 shows the application of such shaping members 1 for creating shapes in the ceiling lining (“lining” in this document refers to the combination of the surface member 7 and the shaping member 1) to facilitate the installation of a light source 13 and reflector 20 and is shown as a cross sectional representation when installed into a plasterboard ceiling (plasterboard being the surface member 7) using a framing system that consists of primary framing members 6 p and secondary framing members 6 suspended with adjustable suspension members 22 from another structural element such as a concrete slab 19.

Referring to FIG. 133, it can be seen that the shaping member 1 has a perforated fixing flange 4 p about its perimeter, which may be fixed the surface member. It can be seen that the primary framing support member 21 has two flanges into which a faming member 6 p may be inserted. The device in total may be supported by a suspension mechanism 22 in a similar manner to the way that the surrounding framing system consisting of members 6 and 6 p is suspended.

FIG. 134 shows the shaping device depicted in FIG. 133 in operation. It can be seen that the ceiling is lined with a building board type surface member 7, preferably plasterboard, which is attached to ceiling framing 6.

This invention allows the surface member 7 (in this case the plasterboard) to be joined with the shaping member 1 in such a way as to form a continuous part of the ceiling lining as no joint is apparent between the shaping member 1 and the surface member 7 when both surfaces are finished with the same paint finish.

To install, preferably suspend the primary framing members 6 p along with shaping member 1 with the use of rods, threaded rods with bolts or any suitable suspension system so that the perforated flange 4 p is in line with the intended face of surface member 7. Normally the device consisting of shaping members 1 and reflector 20 is installed before the primary framing members 6 p are suspended. Insert primary framing member 6 p into support 21 during installation. Fix the secondary framing members 6 to the underside of the primary framing members 6 p. Insert the surface member 7 into the gap between the perforated fixing flange 4 p and the clamping flange 4 c and fix with screws 3. Other fixing devices or techniques may be used so as to ensure a firm connection and prevent any visible movement between the shaping member 1 and the surface member 7. Also fix the same surface member 7 to the faming members 6. Apply settable compound 2 to the junction between the proud protrusion 5 and the surface member 7 to provide a smooth and even surface between the two members. In situations when two shaping members 1 are in close proximity as in FIG. 134 the settable compound 2 may be applied to the connection mechanism between adjacent proud protrusions 5. This may be achieved with the use of an appropriate tool such as a broad knife or a trowel, which is run along the two adjacent proud protrusions 5. If necessary sand the settable compound 2 after it dries to ensure a smooth surface, which preferably should be suitable for a paint finish and should preferably be finished so that no joint is visible after painting.

It can be said that, in this form of the invention, the shaping member 1, as well as shaping the ceiling lining also forms part of the structural support system for the same surface member 7 as well as for the primary framing member 6 p.

It will be realized that the shaping member according to this invention is not restricted to the form illustrated and may be used to form square, rectangular, oblong, curvilinear or any other shapes.

FIG. 135 shows an example, as a cross sectional representation, of a shaping member according to this invention and FIG. 137 shows the gear tray 36 that is part of the same invention.

FIG. 136 shows the same example as FIG. 135 represented as an elevational view looking toward the face of the diffuser 15 of the shaping member 1 according to this invention.

FIG. 138 shows the same example as FIG. 137 represented as a plan view showing the top face of the gear tray 36 of the shaping member 1 according to this invention.

FIG. 139 shows the application of such a shaping device, as a cross sectional representation, when installed into a plasterboard lined ceiling and wall (plasterboard being the surface member 7).

Referring to FIG. 135, it can be seen that the shaping member according to this invention comprises a device of indefinite length. The part of the said invention, which is used to form a joint between the same invention and the surface member 7 is referred to as the covering flange 4 f, which, in this form of the invention, is only seen on one side of the shaping member 1. In this form of the invention the shaping member 1 houses a light source 13 and electronic control equipment 29 for the light source mounted on a gear tray 36. It also utilises a clip-in support 34 to facilitate the fixing of the reflector 20 onto the framing.

FIG. 139 shows the shaping member depicted in FIG. 135 in operation. It can be seen that the wall or ceiling is lined with a building board type surface member 7, preferably plasterboard, which is attached to framing 6.

The fixing flange 4 f allows the surface member 7 to be joined with the shaping member 1 in such a way as to minimise the appearance of the joint between the shaping member 1 and the surface member 7 when both surfaces are finished with the same paint finish.

To install, construct wall framing 6 before suspending the ceiling framing in accordance with FIG. 139 using suspension mechanism 22, primary framing members 6 p and secondary ceiling framing members 6. Provide framing 6 to support the shaping member 1 and the reflector 20. Fix the surface member 7 to the ceiling framing and fix ‘clip-in’ support member 34 preferably with screw 3. Install shaping member 1 in such a way that the covering flange 4 f fits into and fills the rebate in the plasterboard type surface member 7. Standard plasterboard is manufactured with rebated edges on two sides and such a rebated edge should preferably run parallel to the shaping member 1 and butt up against it. Fix the shaping member 1 to the framing member 6 with screws 3 a before installing reflector 20 by resting one side of the said reflector on the shaping member 1 before inserting the opposite end of the same reflector into ‘clip-in’ support 34. Connect electrical gear tray 36 to power supply and fix into position with screws 3 b ensuring to sandwich reflector 20 between the upturn in the same gear tray 36 and the upturned vertical face of the shaping member 1. The gear trays should preferably be positioned so that each light source 13 overlaps the light source 13 of the adjacent gear tray 36 so as to produce a continuous and even glow of light on the reflector 20.

The shaping members 1 in accordance with this invention may be butt joined together end to end so that only a fine line is noticeable at the join or the shaping members may alternatively be joined end to end with a lapping member 35 as indicated in FIG. 136.

Please note that all shaping members that incorporate electrical devices, the connection of the devices to an appropriate power supply is a necessary part of the installation procedure and may be completed at the discretion of a suitably qualified person such as an electrician.

This form of the invention has the advantage that the installation time is less than required for the other forms of the invention that require the application of a settable compound 2 to the junction between the shaping member 1 and the surface member 7 to provide a smooth and even surface between the two members. However an flexible and elastic compound may be used such a mastic type jointing compound commonly available on the market which may be applied preferably between the edge of the coving flange 4 f and the surface member 7. This may be achieved with the use of an appropriate tool such as a broad knife, which is run along the coving flange 4 f and the surface of the surface member 7. After completion the shaping member, joint and surface member should preferably be suitable for a paint finish.

Also preferably adhesive should be applied to the covering flange 4 f and the surface member to which it comes in contact with.

Preferably adhesive should be used to bond the shaping member 1 and surface member 7 in any form of this invention to ensure good bonding between the two members when appropriate.

The shaping member as shown in FIG. 135, in accordance with this invention, is also formed into a reflector 20 which may be made of a flexible material, which may be bent during installation into any suitable radii or shape. This same form of flexible shaping member may be used to join surface members 7 cladding walls to surface members 7 cladding ceilings and the same flexible surface member may be used with fixing flange 4, fixing flange 4 p, and fixing flange 4 p used in conjunction with clamping flange 4 c as well as with coving flange 4 f. The same invention may be used as a reflector or as simply a way of forming a junction between two surface members 7 such as between walls and ceilings instead of using traditional cornices.

As it is formed into shape during installation it may also be used to form shaped or irregular surfaces in walls and ceilings to any design and appear to be continuous with the surface member 7.

This flexible form of this invention may be made of any appropriate material including plastic, PVC, and metal and may also have a patterned or textured surface.

The covering flange 4 f of this form of the invention may be made of a flexible material allowing ease of installation of the surface member. Also the shaping member 1, including the covering flange 4 f may be made of a combination of two materials, preferably a rigid material in combination with a flexible material so that the shaping member may retain its rigidity where necessary and be flexible where desirable.

In any form of the invention it may be desirable to have a rigid body of the shaping member 1 with a flexible covering flange 4 f. It will be realized that the shaping member according to this invention is not restricted to the form illustrated. It may also be incorporated with reinforcing 12 and installed appropriately according to this invention.

FIG. 140 shows an example, as a cross sectional representation, of a shaping member in operation according to this invention and shows a means of joining two shaping members 1 when joined using a framing member 6 to secure the two shaping members 1 relative to each other. The shaping members 1 are configured to incorporate the said perforated fixing flange 4 p which are abutted along the length of a framing member 6 and secured to it with screws 3 or other appropriate fixing devices. After the same shaping members 1 are secured in position in this way a setting compound is preferably applied to the entire face of the perforated fixing flanges and between the two proud protrusions 5 in order to create a continuous surface between the two shaping members 1. The said settable compound may preferably be sanded to ensure that its exposed surface is smooth and in line with the exposed surface of the two adjoining surface members and may preferably be painted to provide a visually continuous surface. FIG. 141 shows an example, as a cross sectional representation, of a shaping member according to this invention and comprises a shaping member 1 with a perforated fixing flange 4 p.

FIG. 142 shows an example, as a cross sectional representation, of a shaping member according to this invention designed to be joined with the shaping member of FIG. 141. The said shaping member of FIG. 142 comprises a shaping member 1 with two perforated fixing flanges 4 p configured adjacent and parallel to each other and separated by a small gap large enough to accommodate the perforated fixing flange of FIG. 141.

FIG. 143 shows the shaping members of FIG. 141 and FIG. 142 in operation, as a cross sectional representation, according to this invention showing a means of joining two shaping members 1. The perforated flange 4 p of FIG. 141 is positioned between the two perforated fixing flanges 4 p of FIG. 142 and the said perforated fixing flanges 4 p may preferably be secured together by means of appropriate adhesive(s) or appropriate fixing devices after which the settable compound 2 may be applied preferably to the entire face of the perforated fixing flange and between the two proud protrusions 5 in order to create a continuous surface between the two shaping members 1. The said settable compound may preferably be sanded to ensure that its exposed surface is smooth and in line with the exposed surface of the two adjoining surface members and may preferably be painted to provide a visually continuous surface. Some or all of the other edges of the same shaping members 1 not joined to another shaping member 1 may be joined to surface members 7 using any of the appropriate methods described herein.

As with the connection of all said shaping members 1 with the said settable compound 2 a fine line may be apparent at the edge of the said proud protrusion 5 depending on the way the settable compound was applied and sanded. If such a fine joint line is noticeable and it is preferable that no said fine line is apparent after having been painted, additional settable compound may be applied to the line and sanded after drying. Additional coats of paint may be applied and sanded between coats after drying.
